NASA's Mars Atmosphere and Volatile Evolution spacecraft (MAVEN) will arrive in orbit around Mars on Sunday, Sept. 21, after a 442 million-mile trek across the solar system. It's one-year mission: to study the atmosphere of Mars in unprecedented detail.
Tonight's MAVEN Mars arrival webcast will run from 9:30 p.m. to 10:45 p.m. EDT (0130 to 0245 GMT), with MAVEN expected to enter orbit around Mars at 9:50 p.m. EDT (0150 GMT).
NASA launched the MAVEN mission in November 2013 in order to study how Mars evolved into its current arid state. The mission aims to understand how the atmosphere of Mars lost much of its water in the ancient past.
SpaceX Launch Replay
SpaceX launched its unmanned Dragon cargo ship to the International Space Station on Sunday (Sept. 21) at 1:52 a.m. EDT (0552 GMT) after a 24-hour delay due to bad weather at its Florida launch site. It is the fourth of 12 launches for NASA by SpaceX under a $1.6 billion resupply contract. This mission will launch more than 2 tons of cargo, and a wealth of science experiments and gear.
SpaceX will use a Falcon 9 v1.1. rocket to launch the upcoming Dragon spaceflight. If all goes well, Dragon will arrive at the International Space Station early Tuesday morning (Sept. 23).
